Table 1. Allowable device types for adding devices to an RDF1 CG
Device type in staging area	Enabled at CG level	Enabled at SRDF group name level
Simple R1 (R1->R2)	Allowed	Allowed
Concurrent R11	Not allowed	Only allowed if both affected SRDF groups in the CG already exist and are assigned to different SRDF group names.
Cascaded R1	Not allowed	Not allowed

Examples

To move devices 50 and 51 from SRDF group 101 in the staging area to SRDF group 100 in R1CG on array 306:

symcg -cg R1CG modify -add -sid 306 -stg_rdfg 101 -devs 50:51 -cg_rdfg 100

To check if the devices were added to R1CG:

symrdf -cg R1CG query -detail
